Specification of Letters Patent. Patented Feb, 1920 Application filed. April 19. 1919. Serial No. 291.186." i

To uZZ;1.t-hm2't'//tay concermn Be it known that 1, JOHN. R. Hnnenn, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in. Calibrating- Machines, of which the' following is a specification. M

The invention relates to a machine for graduating collars, disks, and like work, the mechanism'beingsuch as to insureaccuracy in the graduations and the lengthening of certain marks to facilitate the reading, whereby groups of indications are denoted. The invention provides a machine. of the character stated; which may be readily adapted for marking collars or diskseither on the face or edge, or for marking such parts ha ing beveled edges upon which the markings are to be indicated.

' The drawings illustrate a preferred embodiment of the invention- However, it is to be understood that in adapting the same to meet different conditions, various changes in the. form, proportiomand minor details of construction maybe resorted to without departing from the nature. of the invention as claimed hereinafter. v

Referring to the drawings hereto attached,

Figure l;is a side view of a calibrating machine embodying the invention, the lower portion of the stand being broken away.

Fig. 7 is a detail perspective view ofthe disk provided with an adjustable wrist.

Corresponding and like parts are referred to in the following description and indicated in the several. views. of the drawings by like referenceharacters.

Themachine.coniprisesfa stand-1 to the upper end of which issecuredanbed 2 :upon

which is'. mounted a head 3 and ajpost v4. The bed 2 is provid'e'd at oneend with avertically. disposed sleeve 5- which is split T at oneiside andadapted: to be contracted by means-0r. a clamp screw .6.- The post 4 is mounted in the sleeve 5' and is adjustable vertically andlis secured in the. adjusted pocal sectionon the'line sition by contracting the sleeve 5 by means ofthe clamp screw"6.. Theipost 4 is tubular-land is prevented from turning. in the sleeve-5 by means of a key which coacts .Wlth a groove formed in the inner wall of the. sleeve 5. Rack teeth 8 are formed on one side of the post 4 and coacts with a pinion 9 provided. on ashaft '10 which is mounted in bearings of the sleeve 5. and

which is providedat its outer end with a hand wheel 11. l/Vhen the clamp screw-6 is 1 loosened the post'4' may be vertically adjustedby operating the shaft 10 which r0- tates the pin-ion9 and through the instrumentality of the rack teeth 8raises or lowers the post; ed to the required position it is madelsecure by 'retightening the clamp screw '6 which contracts the sleeve 5 and bindsthge When the post 4 has been adjustpost 4. shaft 12-is rotatably mounted in the'post 4 and is providedatits upper end with afiange 13 and .a'tlireaded stem 14, the fiange13 overlappingithe post 4 toQprevent downward displacement of the,..shait and the stem 14 being adapted to receive the work or a head '15 which terminates in a threaded stem 16 upon which the work may low the sleeve 5 and .supports'ashaft. 18 and a worm gear-l9, the latter meshing with av worm 20 on the shaft '18.: The worm gear 19 is keyed to the-lowerend of the shaft 12 so as to rotate therewith and isin. mesh with the threads of the worm .20.. :The .ringc1-7-., I

and parts carried thereby fmove vertically with the post 4; 'A lever 21 is pivotally mounted upon the projecting end ,of the shaft 18 and is provided-at one endv lWithfa springactuated dog 22 and has a "rod 23 pi v;- otally connected with its opposite end; A

ratchet wheel 24 is secured to the projecting end of theshaft 18 so as to rotatetheiiewith roe and is adapted to be intermittently actuated ratchet wheel 24 .the.graduati0ns-of the sion formed in the bed 2 and in which is located' the screw 25. cured to the outer end of the screw. 25 provides convenient 'means for rotating *the understood.

Ahand wheel 27 se screw toeffect adjustment of the head 3. A guide member .28 1s pivotally connected to the head 3 to admit of the marker being adjusted to suit the nature of the work. The

guide member 28 is pivotally mountedupon a shaft 29and is adapted to be secured in the adjusted position by suitable fastening means. Z" The head 3 comprises a base and uprights and one of the latter is formed with an arcuate slot 30 in which operates a bolt or like fastening 31. When the fastening 31 is loosened the guide member 28 maybe turned on the shaft 29 to the required adjusted position to adapt the marker to the work. One of the uprights of the head 3 hasits edge formed on the arc of a circle concentric with the shaft 29 and provided with graduations '32, whereby to facilitate the setting of the guide member 28 when adjusting the same to a given angle. The shaft 29 is provided at one end with a hand wheel 33 and at its opposite end with a disk or wheel 34 which is provided upon its outer side with a diametrical guideway 35 which receives an adjustable wrist 36 upon which is mounted a sleeve to which the rod 23 is adjustably connected. Adjustment of the wrist 36 in the guideway 35 to a greater or less distance from the axis ofithe shaft .29 results in varying the throw of the lever21 and movement of the ratchet wheel 24 at each operation thereof. When adjusting the 7 post 4' vertically the means connecting the rod 23 to the sleeve 37 is loosened-so that-the rod 23 may movexwith the lever 21 in conformity to the vertical adjustment of the post 4. WVhen the post 4 has been adjusted to therequired position it is made secure by operating the clamp screw 6 in the manner rocatory movement.

stated and the rod 23 is made fast to the sleeve 37 so that in the rotation of the shaft 29 vibratory movement may. be imparted to the lever 21, the rod 23 being connected to the sleeve 37 which in turn is loosely mounted on the wrist 36.

The guide member 28 receives a holder 38 which is mounted therein to receive arecip- The holder 38 carries the marker 39 which consists of a cutting tool such as usually provided in connection with machines for marking or calibrating metal. The marker 39 is adjustable. and detachable from the holder 38, whereby to admit of sharpening and replacement. A pin 40 projects laterally from the holder 38 and passes through a vertical slot 41 formed in side of the guide member 28. A contractile helical spring 42 is connected at one end to the pin 40 and at its opposite end to a pin 43 which projects from the. guide member'28. The pin 43 alsoserves as a stop to limit the downward movement ofthe holder 38. p The holder 38 is moved vertically by means of'a toothed wheel44 which is mounted on a pin 45 carried by the guide member 28. The teeth of 'the toothed wheel 44 cooperate with the holder 38 to move the same upward against the tension of the spring 42. A wheel 46 is secured onthe shaft 29 to rotate therewith and is provided with a pin 47 which'is adapted to engage the teeth of the wheel 44 and impart an intermittent rotary movementthereto; whereby to eifectarecip- .rocating movement of the holder 38 and the marker carried thereby. The wheel 44 maybe provided with. any number of teeth, but'one tooth as 44 is made longer than'the distance, whereby the mark made by the element 39 1s longer than the remaining marks. Thus the graduations are mdicated in groups with the result that the reading is greatly facilitated. As indicated most clearly in Fig. 6 the wheel 44 is provided with four short teeth of equal length and one long tooth, hence the graduations will have. every fifth'mark longer. than the remaining marks, 7 whereby the indications may be read quickly 1 remaining teeth. to lift the holder 38 a greater 39 may be adjusted to the work. When the marks are to be formed on the edge of a disk wheel or collar which is parallel with.

the axis of the part, the guide member 28 is adjusted to cause the holder 38 to reciprocate in a direction parallel with the axisv of the shaft 12. If the edge of the collar, disk or like part is inclined the guide member 28 is adjusted to the proper angle so that the cutting edge of the marker 39- will engage the edge of the work. 1 If the graduations are to be formed on a side of the dislgcollar or the like, the guide member 28'isturned to occupy a horizontal position, whereby the marker 39 will operate in a plane at a right angle to the axis of the shaft 12. It is'to be understood that the post 4 will be adjusted verti callyto bring the work in proper position ma am invention.
